Microsoft's Touch Covers double as pressure-sensitive keyboards and protective covers. They magnetically hold in place and have a standard keyboard layout with shortcut keys. They also have a two-button touchpad that supports gestures. It's not yet clear if the company's version for iPad would look or even work similarly. We can only safely assume it has a lithium-ion battery.

It therefore could connect over Bluetooth, or it could work with the iPad Pro's Smart Connector. If we had to guess, Microsoft will probably make the Touch Cover work without the Smart Connector, because then it could cater to regular iPad owners who can't use Apple's smart keyboard. But keep in mind Microsoft might never announce this product. We've only seen one leak, after all.
